This 5th edition of Financing and Charges for Wastewater Systems provides an overview of current industry practices that should be considered for financing and establishing rates and charges for wastewater collection and treatment systems. In addition, this Manual of Practice reflects and is responsive to changes in the industry over the past 6 years that have occasioned a heightened awareness about wastewater utility financial management, the rapid rise in cost of operations and capital investment, and the increased scrutiny of equitable distribution of cost responsibilities across customer groups or classes. These events and changes, including tightening environ mental regulation and replacement of aging infrastructure, have resulted in a pronounced increase in the cost of wastewater services. Though there have been several federal initiatives over the past 6 years to infuse funding to the wastewater sector, costs have outpaced available funding and assistance and challenge the affordability of this vital service. In this context, guidance on wastewater rate-setting practices and, particularly, the distribution of costs across user groups are of critical importance. As individual wastewater utilities address their financial-management challenges, it is important that their practices for setting rates and charges be responsive to the unique circumstances and values of the communities they serve. Accordingly, this manual offers industry-accepted guidance in addressing these challenges without prescribing specific methods. In many instances, acceptable methodological alternatives are presented. Financing and Charges for Wastewater Systems is structured to provide the reader with an overview of financing mechanisms for wastewater systems and a framework for development of wastewater rates and charges.

This technical publication provides comprehensive guidelines and insights for the planning, design, operation, and maintenance of anaerobic co-digestion systems. The practice of co-digestion of wastewater residuals with high-strength organic wastes and harnessing the resulting biogas has been adopted by a growing number of water resource recovery utilities, particularly over the last decade. This technical publication intends to equip engineering and design professionals, researchers, operations and maintenance staff, educators, and students with a detailed understanding of fundamental concepts and practical applications of anaerobic co-digestion.

Wastewater Treatment Fundamentals I: Liquid Treatment, 2nd edition covers all aspects of liquid treatment processes and helps operators prepare for the first three levels of certification examinations. In addition to learning the basics of liquid treatment, operators will gain a thorough understanding of critical aspects of biological treatment, nutrient removal, and disinfection. After learning from real-life examples, users can apply the material they learn to situations they encounter in their day-to-day work. Wastewater Treatment Fundamentals I: Liquid Treatment, 2nd Edition includes: -Detailed visuals and infographics -Comprehensive math examples -Practice questions for each module with lots of variety -Accessible language for all levels of operators This self-study manual aligns with updated Need-to-Know Criteria from the Water Professionals Institute (WPI) and are based on WEFs extensive existing resource collection.

This book is intended to help water and wastewater utility managers and operators navigate the complex world of cybersecurity. It provides accessible guidance on how utilities of all sizes can manage their risks, focus their resources, and implement controls to keep their facilities and their communities safe. This includes creating a culture of good cybersecurity internally and managing relations with third-party contractors.

Standards for Operation of Nutrient Removal Facilities, WEF 37-24, covers the fundamental biological and chemical processes that are in use at nutrient removal facilities and the ways that operators may use, monitor, and control these processes to meet their facility’s treatment goals. It is a valuable resource not only for plant managers and operators, but also design engineers and regulators. This latest edition references the most up-to-date technologies and practices for nutrient removal and includes both new and updated case studies.

Automation has become an integral component of water treatment, with new technologies and applications constantly being developed and producing increases in efficiency and reliability. Standards for Automation of Water Resource Recovery Facilities, 2nd Edition, WEF 21-24 introduces the reader to the elements of complete automation design and the standards that govern those elements. Ideal for designers, utility managers, and operators.

This resource presents the best practices for the use of membrane bioreactors for wastewater treatment. The book begins with an overview of membrane and biological process fundamentals, followed by coverage of membrane bioreactor system integrated process design. The chapters discuss the physical design of features unique to membrane bioreactors and the procurement of membrane equipment. This authoritative manual also covers the operation of properly designed membrane bioreactor facilities.

Wastewater Engineering: Design of Water Resource Recovery Facilities (MOP 8 Series) provides the reader with the up-to-date knowledge and tools required to design water resource recovery facilities. It serves as both a textbook for senior level and graduate students in civil engineering and a reference work. The scope of coverage and the classroom-friendly features, such as learning objectives and example problems, makes it an excellent tool for students transitioning from academia to practice, and it remains an essential resource for practitioners. Written by a team of professors and consultants and put through a rigorous industry review, Wastewater Engineering provides vital WRRF design information to an engineer at every stage of their education and career. Wastewater Engineering has its roots in WEF’s Design of Water Resource Recovery Facilities (MOP 8), a long-time fixture on the design engineer’s shelf. As WEF approached how to update MOP 8, the organization decided to do so in a way that would address two significant needs in the water sector. The first was the need for current, nationally applicable, peer-reviewed design standards. The result was Standards for Design of Water Resource Recovery Facilities (WEF 8). WEF 8 is a tool for seasoned design professionals, providing concise coverage of critical design criteria that has been formatted in quick-reference tables and bulleted lists. The second was the need for a wastewater design textbook and reference, as covered by this book. Within the MOP 8 series framework, this textbook serves as the entry point for new wastewater engineers and a primary reference work for practitioners, providing both theory and significant context behind the design parameters covered more briefly in WEF 8.

Water resource recovery facility operators and maintenance staff are responsible for the protection of the environment and public health by ensuring excellent process control and equipment function.
